The legacy verifier, used by the deprecated login method, compares clear-text passwords, crypt hashes and base64 digests with eq, so the comparison time depends on how many leading bytes match.\n\nA remote attacker can use response-time differences to guess the stored password or hash.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-208"],"vendors":[],"products":[],"references":[{"url":"https://github.com/perl-catalyst/Catalyst-Plugin-Authentication/commit/ba4435f1fa6b641e6c8793c88b5433afa83ceafa.patch","tags":[]},{"url":"https://metacpan.org/release/ETHER/Catalyst-Plugin-Authentication-0.10029/changes","tags":[]},{"url":"https://www.cve.org/CVERecord?id=CVE-2026-5091","tags":[]}],"exploitRefs":[{"url":"https://github.com/perl-catalyst/Catalyst-Plugin-Authentication/commit/ba4435f1fa6b641e6c8793c88b5433afa83ceafa.patch","tags":[]}],"hasPoc":true,"ai":null}
